AJS Model 31
The AJS Model 31 was a British motorcycle made by Associated Motor Cycles at the former Matchless works in Plumstead, London. Developed in 1958 specifically to capture the potentially lucrative US market, the last Model 31 was produced in 1966. Development AJS Model 31 The AJS Model 31 was also produced as the Matchless G12 by the same company. Designed by Phil Walker, AMC knew that it had to be a 650cc but wanted to use as many cycle parts as possible from the preceding 600cc Matchless G11, which had been badge-engineered as the AJS Model 30. The cylinders could not be bored out further, so the stroke was lengthened from 72.8mm to 79.3mm, increasing capacity to 646cc. That meant developing a new crankshaft and primary chaincase, which also provided the opportunity to add a Lucas alternator. Volume production began in September 1958. AJS Model 31 De Luxe In 1959 the Model 31 was redesigned and modernised as the ''De Luxe'', with a new full cradle tubular duplex frame and ...

Associated Motor Cycles
Associated Motor Cycles (AMC) was a British motorcycle manufacturer founded by the Collier brothers as a parent company for the Matchless and AJS motorcycle companies. It later absorbed Francis-Barnett, James, and Norton before incorporation into Norton-Villiers. Henry Herbert Collier founded Matchless as a cycle company in 1878. His sons Henry (Harry) and Charles (Charlie) joined him and the name was changed to H. Collier & Sons. History AJS had been bought by Matchless's owners, the Colliers, in 1931 and Sunbeam was added in 1937 from Imperial Chemical Industries. The name of the Matchless Motor Cycles company was changed to "Amalgamated Motor Cycles Ltd" in 1937 and "Associated Motor Cycles (AMC)" in 1938. AMC was not a manufacturer in its own right, but rather the parent company of a group of motorcycle manufacturers which included Matchless, AJS, Norton, James, Francis-Barnett, Sunbeam and others. In 1939 a 495 cc AJS V4 was built to compete against the supercha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumstead
Plumstead is an area in southeast London, within the Royal Borough of Greenwich, England. It is located east of Woolwich. History Until 1965, Plumstead was in the historic county of Kent and the detail of much of its early history can be found in Edward Hasted's extensive history of Kent. In 960 King Edgar gave four plough lands, collectively called Plumstead, to a monastery - St Augustine's Abbey near Canterbury, Kent. These were subsequently taken from the monastery by Earl Godwin for his fourth son, Tostig. King Edward the Confessor restored them again to the monastery on taking power, however Tostig saw the opportunity to take possession of them once again after Edward's death in 1066 when King Harold seized his brother's estates. After the Battle of Hastings in 1066, William the Conqueror gifted Plumstead to his half-brother Odo, Bishop of Bayeux, whom he also titled Earl of Kent. The Archbishop of Canterbury Lanfranc of Pavia and the Norman abbot of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now const ...

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matchless
Matchless is one of the oldest marques of British motorcycles, manufactured in Plumstead, London, between 1899 and 1966. A wide range of models were produced under the Matchless name, ranging from small two-strokes to 750 cc four-stroke twins. Matchless had a long history of racing success; a Matchless ridden by Charlie Collier won the first single-cylinder race in the first Isle of Man TT in 1907. In 1938, Matchless and AJS became part of Associated Motorcycles (AMC), both companies producing models under their own marques. During the amalgamations that occurred in the British motorcycle industry in the 1960s, the Matchless four-stroke twin was replaced with the Norton twin, ending a long history of independent production. By 1967, the Matchless singles had ceased production. History The first Matchless motorcycle was made in 1899, and production began in 1901. Matchless was the trading name of Collier & Sons, the father Henry Herbert Collier and his sons Charlie and H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rebadging
In the automotive industry, rebadging is a form of market segmentation used by automobile manufacturers around the world. To allow for product differentiation without designing or engineering a new model or brand (at high cost or risk), a manufacturer creates a distinct automobile by applying a new "badge" or trademark (brand, logo, or manufacturer's name/make/marque) to an existing product line. Rebadging is also known as ''rebranding'' and ''badge engineering''; the latter is an intentionally ironic misnomer, in that little or no actual engineering takes place. The term originated with the practice of replacing an automobile's emblems to create an ostensibly new model sold by a different maker. Changes may be confined to swapping badges and emblems, or may encompass minor styling differences, as with cosmetic changes to headlights, taillights, front and rear fascias and outer body skins. More extreme examples involve differing engines and drivetrains. The objective is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucas Industries
Lucas Industries plc was a Birmingham-based British manufacturer of motor industry and aerospace industry components. Once prominent, it was listed on the London Stock Exchange and was formerly a constituent of the FTSE 100 Index. In August 1996, Lucas merged with the American Varity Corporation to form LucasVarity. After LucasVarity was sold to TRW the Lucas brand name was licensed for its brand equity to Elta Lighting for aftermarket auto parts in the United Kingdom. The Lucas trademark is currently owned by ZF Friedrichshafen, which retained the Elta arrangement. History Foundation In the 1850s, Joseph Lucas, a jobless father of six, sold paraffin oil from a barrow cart around the streets of Hockley. In 1860, he founded the firm that would become Lucas Industries. His 17-year-old son Harry joined the firm around 1872. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nodular Iron
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its ''nodular graphite'' inclusions. On October 25, 1949, Keith Dwight Millis, Albert Paul Gagnebin and Norman Boden Pilling received US patent 2,485,760 on a cast ferrous alloy for ductile iron production via magnesium treatment. Augustus F. Meehan was awarded a patent in January 1931 for inoculating iron with calcium silicide to produce ductile iron subsequently licensed as Meehanite, still produced . Metallurgy Ductile iron is not a single material but part of a group of materials which can be produced with a wide range of properties through control of their microstructure. The common defining characteristic of this group of materials i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AJS 7R
The AJS 7R was a British 350 cc racing motorcycle built from 1948 to 1963 by Associated Motor Cycles. It was also commonly known as the ‘Boy Racer’, and won victories both for the factory and for privateers right from its introduction in 1948. The AJS 7R A new design by Phil Walker, the chain-driven overhead camshaft 7R had the history of the pre-war AJS ‘cammy’ singles behind it. Initially, the 7R was not quite as powerful as its competitors, producing at 7500 rpm. The duplex frame and Teledraulic front forks remained relatively unchanged during production, while the engine had a number of changes. The included valve angle was progressively narrowed, and the crankshaft strengthened. In 1956 the engine dimensions changed from the original long-stroke 74 x 81 mm to the ‘squarer’ 75.5 x 78 mm. The AMC gearbox replaced the older Burman unit in 1958. AJS 7R3 In 1951 AJS development engineer Ike Hatch developed a 75.5 mm bore x 78 mm str ...

Thruxton 500
The Thruxton 500 was a motorcycle endurance race for production based road machines, covering 500 miles and ridden by a team of two riders per machine. The first event was a 9-hour race which took place in 1955, organized by the Southampton and District Motorcycle Club (SDMCC) at the Thruxton Circuit near Andover in Hampshire. Two more 9-hour races followed in 1956 and 1957. These earlier 9-hour races resulted in the birth of the famous Thruxton 500 miler, the first taking place in 1958 and the last in 1973. The Thruxton 500 was an endurance race for production based road machines, covering 500 miles and ridden by a team of two riders per machine. There were twelve Thruxton 500 events between 1958 and 1973. During that period, there were four races where the 500 miler had to be run at two different circuits because of poor track conditions at Thruxton. The first rearranged 500 miler race was at Castle Combe in 1965 followed by three other meetings at Brands Hatch in 1966, 1967 a ...
